[Closed] Anyone got an Elite Super Crono digital turbo?

Just picked one up from decathlon for £150 quid. Seems ok, but it says you 'adjust the training effort by selecting the desired resistance' through the cable lever, but also 'use side button on the computer to 'vary required resistance'. Eh???? Isn't that the same thing.

The later does precisely nothing as far as I can see. Likewise there is a slope % readout, which I assumed would be used to alter intensity, but it just randomly changes depending on how I pedal, ie I can't set the gradient manually.

Any pointers?
